` SPOOL.

Appligation filed AprilH 9, 1925, Serial' No. 21,946.' Renewed November8, 1928.

This invention relates to an improved construction of spool, reel or thelike on which wire or other materia-l may be wOund; and

v the object of thisinvention is to provide such a-spool having atubular body with a head at each end thereof, the inner faces of theheads being recessed to receive the ends of the body portlon to preventVrelative rotation between them, independent means being 4also providedfor locking or securing the heads to the boy ith 'thesefand otherobjects in view, the

invention consists of certainnovel features of yconstructioxn-as will bemore 4fully described,and-particularly pointed out in the ap endedclaims. .u

body member as illustrated yin Figure 5.

It is 'found in the practical'enstruction of spools of this character,of advantage to provide a body member with heads at opposite endsthereof and to provide the inner faces of the heads with recesses forthe reception of the ends of the body member and to so forni theserecesses as to provide one or more keys or means for lpreventingrelative rotation be- Atween' the body and the heads; also in somecases, it is foundof advantage' to provide a. filling of Wood or othersuitable non-metallic material s et into'the outer faces of the headplates and to also provide a collar-plate secured to the outer fane ofthe filling member to which a tubular ,eqre'or other member may besecured forvthe purpose of tying the head members onto the body. ln somecases one of the flanged heads may be grooved to recelve a drivingbeltyand the following is a detailed description of the presentembodiyment of my invent-ion showing one means by which theseadvantageous results may be accomplished With reference to the drawings,10 designates the b ody of my improved spool which ispreferably formedof sheet metal rolled into tubular form with the ends of the tubeforming a lap joint v11 at the seam, and on the ends of this bodymembenl preferably mount head members 12each formed from sheet stockcomprisin an inner 'disc' plate 13 having an out-turne peripheral flange19 with an inturned 'edge 20. The inner faces .of the disc plates arepreferably provided i with an annular groove 14 for the reception ofthe-ends of the tub lar body 10. This an- Anular groove is also providedwith an en-4 largement 1 5, see Figure 3, for the reception of the lapjoint portion 11 of the body. The 'shouldersl of this enlarged recess 15are for engagement with the shoulders 17 on the lap joint of the seam11, whereby when this lap joint portion is inserted into thisenlargement 15 in the annular recess of the v head, it serves as a keyto prevent relative rotation .between the head and the body.v

In some cases it is found of advantage to p rovide a filling 18 ofnon-metallic material in the outer faceof the head member such as wood,vulcanized fibre or other similar material over which the outer edge 20of the flange is turned. A` lt is also found of ad- 9 vantag to secure acollar-plate 21 to the 95 .outer face of the lling by forming spurs 22bers and the edges 20 of the flange 19v rolled Over onto the before thehead members are positioned onrto the body and after the ends of thetubular core are riveted or rolled to bind' the Whole together.

I do not wish to be restricted tothe use of over onto the outerfacesofthe head members non-metallic material as a filler for the headsas this maybe omitted, if desired, and any other suitable cdnstructionmay-be employed, neither do I Wish to be restricted to the emplyment ofa central or tubular core 23 as any other. suitable means may beemployed for securing `the heads ontothe body of this spool. A f

Instead of forming a continuousc annular I having recesses for receivingthe ,ends of saidv body and provided With an outwardly-turned groove inthe side faces of the head plates for the reception of the ends of thetubular body, I may form slight projections 23 on the ends of the tubeas shown in Figure 5,

and provide corresponding recesses 24 in the head plates, as illustratedin Figure 6.

In some instances I may provide an annular groove 25 in the'periphery ofone of the spool 'heads for the reception of the driving belt,

if desired.

i My improved lsp-ool is very simple, practical j The foregoing towardsthe' construction illustrated but I and inexpensive in constructio-n, isvery easy to .assemble and 1s very strong and durable in its operat1on.-

description is directed solely desire vit to be understood that Ireserve the privilege of resort-ing'tol all 'the mechanical changes towhich the device is susceptible, the invention being ldefined andlimited only by the terms of the appended claims.

I claim: l 1. A spool having a rolled sheet metal tubular `body with 'aseam longitudinally thereof and a projecting portion adjacent the seamat the end of said body, a head 'at 'sich end of thebqdy, the inn-e1faces of said heads having imperforate recesses to receive i relativerotation of the body andA heads and I' joint seam, the inner faces ofsaid heads be.

said projecting portion adjacent the seam and lock the seam closed and'also prevent means for lockingfsaid heads onto the ends of said body.. vl

2.- A spool having@ bdy' with@ heid ai.: eachend, said body being formedof sheet metal rolled into tubular form With a lap ing each providedwith an annular recess into which the ends ofthe tube extend and 1 withan enlargement for the joint portion,

' ingand the part-s 4are prevented from relawhereby the joint isprevented from spreadtive rotation, and means for securing the heads tothe ends of the body.

3. A spool having a body with a head at each end, said body being formedof sheet metal rolled into tubular form With a lap joint seam Withv lan`invvardly-extending shoulder, the inner faces of said heads being eachpro-vided with an annular recess into which the ends of the'tube extend,andan peripheral flange, anonmetallic lling secured in each of saidheadsbyy its flange, a

core for securing said members .in assembled. relation, and means forpreventing the relative rotation-of said members.

5. A spool comprising a tubular body member, head members at each endthereof having outwardly extending ianges, a nonmetallic filling`secured n in each'head by its fiange and having a centralopeningtherethrough, a collar-plate' on the outer surface of saidlling.andllocated about said opening, and a core extending through `saidbody having its ends engaging said collar plates to hold the members inassembled relation.

. 6. A spool comprising a tubular body member, head members at each endthereof, each having an outwardly-turned peripheral Harige,anon-metallic filling in each head 'and the edge of said flange turned'inwardlyv therein, said heads having af central opening therethrough, acollar-plate on the; outer surface of said filling and located aboutsaid opening, and a tubular core extending Ythrough said body havingitsends engaging said collar-plate to lock the heads onto the ends of thebody.

,7. A spool haying a tubular body With liead members at each end, meansfor preventing relative rotation of'the heads and body', non-metallicouter face on said heads,

a'collar plate on the outer surface of each of said faces havinginturned spurs eX- tending thereinto vand a tubular core exi tendingthrough the body and headmembers and engaging said plates to lock saidhead members on to the body.

In testimony whereof I aiiix my, signature.
